Add Contents::ReplacedWithWidget for video elements with UA control widget, to allow Traverse into the children of video element during Box Tree Construction, Generate IndependentFormattingContextContent::ReplacedWithWidgets, to store both the `ReplacedContents` and `BlockFormattingContext`. During fragment tree generation process, first layout the Image Fragment, and then Layout the Inner Controls BlockFormattingContext. Doing this allow us to determine the size of Inner Controls widget based on the size of the Image Fragment. Minor Fix: ::before/::after pseudo elment should be suppress for replaced element. Testing: Should show the controls widget for `<video controls></video>`, and should not affect any existing WPT test. Since how to display UA widget of Video Element is not defined in the spec, expectedly there has no existing WPT test that testing this.
